the hepquant shunt test for monitoring liver disease and treatment effects by measuring liver function and physiology

Conditions: NASH - Nonalcoholic Steatohepatitis

Summary: the hepquant shunt test, which is provided as a hepquant shunt liver diagnostic kit, is a minimally-invasive test of liver function and physiology which has been designated by the fda as an investigational drug/device combination product. enrollment into one of the 3 gilead selonsertib clinical trials (gs-us-416-2124, gs-us-384-1943/1944) is required for enrollment into the hepquant study

the hepquant study is to run parallel to the gilead clinical trials,gs-us-416-2124 trial of alcoholic hepatitis, gs-us-384-1943 trial of non-alcoholic steatohepatitis (nash) fibrosis stage 3 (stellar-3), and, gs-us-384-1944 trial of nash and compensated cirrhosis (stellar-4). the time points for the hepquant shunt tests coincide with pre-specified time points within the gilead clinical trials. subjects enrolled in gilead's stellar and alcoholic hepatitis trials may participate concurrently in this hepquant sponsored investigational device study at participating us sites only (ides as listed above) once approved by the applicable irb/iec. the main eligibility criteria for enrollment into the hepquant study is enrollment into one of the three gilead clinical trials listed above. the hepquant shunt test is minimally-invasive and measures hepatocyte function and inflow to the liver from the simultaneous clearances (hepatic filtration rates, hfrs) of cholate from systemic and portal circulations. the test quantifies portal-systemic shunting (shunt) and generates a liver disease severity index (dsi). dsi is a score from 0 (no disease) to 50 (terminal illness) that is a composite of both hfrs and correlates with stage of fibrosis, presence of varices, especially large varices, and risk for future clinical outcomes. dsi is the primary output variable from the hepquant shunt test. the hepquant shunt test potentially satisfies the unmet medical need for a minimally-invasive test of global liver function and physiology

Eligibility criteria:
inclusion criteria: the key inclusion criteria for this hepquant parallel study are the inclusion criteria into one of the gilead selonsertib trials (gs-us-416-2124, gs-us-384-1943 or 1944). once that has been met, subjects must: * be able to ingest liquid by mouth * have venous access to support a peripheral iv and 6 blood draws exclusion criteria: the key exclusion criteria for this hepquant parallel study are the exclusion criteria for one of the gilead selonsertib trials (gs-us-416-2124, gs-us-384-1943 or 1944). if this has been met, the subject is not eligible to participate in hepquant. if no exclusion criteria has been met for the gilead selonsertib trial, additional exclusions for hepquant are: * subject should not have had first dose of selonsertib * subject cannot take anything by mouth * subject cannot be hypersensitive to eggs, albumin preparations, any ingredient in the formulation, or component of the container * subject cannot have intercurrent medical or surgical illness (eg: acute mi, acute cerebral hemorrhage, sepsis) * subject cannot have had extensive resection of large segments of small intestine (short gut) * subject cannot have severe gastroparesis
